This module is thought for sending and receiving audio signals. I use it to add some external effects to my modular. Albeit simple, it is very useful. For connecting pedals and external CV sources I recommend my Pedal/CV Send and Receive module.

Specs and features

  • Attenuates the out signal to line level
  • Amplifies the input signal to modular level
  • Amplitude control for in and output
  • Runs on +/-15V and +/-12V without changes
  • Power consumption around 10mA each rail

The documentation and the Gerber files for download can be found in my website.
